Each of the plurality of sealing pads includes a flow-restriction tab having an axial thickness that varies as proceeding circumferentially around the mandrel. The flow-restriction tab of each of the plurality of sealing pads is configured to be disposed in the flow-restriction recess when the plurality of sealing pads are disposed on the mandrel.
